Title: Cathode-ray tube beam controlling device
IPC: H01J29/70
Filed: 1964-08-14
Abstract: 1,077,412. Cathode-ray tubes. ZENITH RADIO CORPORATION. Aug. 14, 1964 [Aug. 14, 1963], No. 33326/64. Heading H1D. A device for varying the effective point of origin of the electron beam of a cathode-ray display tube, particularly a short, three-gun, shadow-mask, colour tube, comprises magnetic means, located on a support surrounding the tube intermediate the centre of deflection and the screen, for developing an auxiliary deflection field such that the integral of the curve of the field strength component transverse to the beam path times its distance from the deflection centre along the beam path as a function of said distance is the same along all beam paths. Such a field may be produced by two semicircular ferromagnetic bars 30, 31, Fig. 2, magnetized to provide a plurality of radial magnetic pole pairs as shown. The bars 30, 31 may be rigid or resilient and are secured to a plastic ring 32. Alternatively, a plurality of permanent magnets (60, 61, Fig. 6, not shown), may be secured to a plastic ring, the sizes, magnetic strengths and circumferential positions of the magnets being such that the effective field strength of the magnetic pole pairs varies sinusoidally as a function of circumferential displacement. A similar field may be produced by four semicircular magnetic strips  (80-83, Fig. 8, not shown). Two similar ring magnet arrangements are rotatably mounted adjacent one another around the screen end of the deflecting coils to provide a beam positioning field of variable intensity and direction. To enable the two rings to have a common magnetic centre, the rings may be slightly twisted, Fig. 23 (not shown), and assembled back-to-back, or the magnetic axis of each pole pair of each ring may be canted with respect to the plane of the ring. Alternatively, the magnetic field of the ring nearer the screen may be slightly weaker than the field of the other ring.

Title: Apparatus for adjusting the diameter of tubular films
Inventor: BELLONI ANTONIO
IPC: B29C48/92
Filed: 1962-09-05
Abstract: 1,017,398. Tubular films. I.C.P.M. INDUSTRIE CHIMICHE PORTO MARGHERA S.p.A. Sept. 5, 1962, No. 34011/62. Heading B5B. A device 8 for adjusting the diameter of tubular films made by inflation comprises an injector 1 supplied with compressed gas via tube 7, a variable pressure chamber 2 communicating with the interior of the bubble 6 by a connecting tube 3-3<SP>1</SP>, and a revolvable pierced mask 4 coaxial with the injector chamber and integral with a skid or shoe 5 resting against the exterior of the bubble 6. Chamber 2 has a hole 102 the aperture of which can be increased or decreased by rotation of mask 4, fitted with a correspondong hole 104, about the surface of the shell 203. Shell 203 is carried by arm 11 which is revolvably supported by support 110, which, through location screws 10, enables the inclination of arm 11 to be adjusted. In operation, the melt enters nozzle 30 via tube 9 and is extruded to form a bubble 6, inflation gas being supplied via tube 7, chamber 2 and tube 3-3<SP>1</SP> to the bubble interior. A proportion of the gas leaks out via holes 102 and 104 which normally partially overlap. Should the bubble diminish in volume the skid 5 falls, partially or wholly closing the leak and thus increasing the pressure of the gas supplied to the interior of the bubble. Should the bubble increase in volume the skid 5 rises, further opening the leak and thus reducing the pressure of the gas supplied to the tube interior. Skid 5 may be arranged to fall under its own weight or by the action of springs. Bubble diameter may be varied by altering the inclination of the supporting arm 11, and the sensitivity of the apparatus, i.e. the promptness with which it intervenes may be adjusted by inclining the shoe arm or by adjusting the pressure exerted by the shoe arm on the tubular film.

Abstract: 604,656. Automatic exchange switches. LEICH ELECTRIC CO. Dec. 21, 1945, No. 34798. Convention date, June 11. [Class 40 (iv)] In cross-bar switches of the types disclosed in Specifications 544,954, 601,965 and 615,312, the trunk units are disposed half on either side of the test and terminal units. In cross-bar switches of this type, 300 bars, being the line and test bars for 100 subscribers in a linefinder or final selector or 100 trunks in a group selector, are arranged in a rectangular array of 30 x 10 and trunk units are disposed along the length of the bars, arrangements being made for each trunk unit to connect an associated trunk selectively with a particular set of three bars. In the prior arrangements, a test and terminal unit in the case of line-finders, and a terminal unit only in the case of group and final selectors is situated at the end of the row of trunk units, connections between the bars and outside cabling being made through clips from which the bars can be readily withdrawn, as may be necessary for replacement of faulty trunk units or the addition of new ones. To avoid the total disablement of the switch in such circumstances, the present invention disposes the trunk units half on either side of the terminal unit, the bars being split into halves separately withdrawable so that only half of the trunk units need be disabled when repair &c. of a trunk unit is necessary. Fig. 2 shows the top three bars 50 ... 52, 50a ... 52a of one of the 10 columns of 30 bars with trunk units 1 ... 4 (not shown) and 5 situated on the left and trunk units 6 and 7 ... 10 (not shown) on the right of a test and terminal unit. The bar 50 is held between but is capable of withdrawal from prongs 68, 69 whose extension 66 passes through the insulating supporting frame 64, being held in position by the springy tab 67. The double set of prongs 80, 81 and 82, 83, which may be positioned into the insulating frame 65 when the latter is moulded, similarly receive the extension 66 and the bar 50a. Connections to the external cabling 111 are made to a suitable soldering tab at this point. In a switch unit not requiring a test unit, the bar 50 is inserted directly between the prongs 80, 81.
